摘要:
A computer implemented method and apparatus for managing aircraft software parts. An aircraft software part management apparatus comprises a library, a receiving module, a proxy server, an onboard electronic distribution system on an aircraft, and a portable software maintenance tool. The library on the ground data processing system stores and manages aircraft software parts for aircraft. The receiving module is capable of receiving the aircraft software parts from suppliers and sending the aircraft software parts to the library. The proxy server is in communication with the library and is capable of distributing software to a plurality of aircraft clients. The onboard electronic distribution system is an aircraft client and is capable of receiving aircraft software parts for the aircraft from the library through the proxy server. The portable software maintenance tool provides an alternate route to send the aircraft software part to the onboard electronic distribution system for the aircraft.
摘要:
A computer implemented method, apparatus, and computer program product for managing aircraft software parts. A connection is established between a portable data processing system and a source through a ground network. Uplink commands are retrieved from the source through the established connection. Aircraft software parts corresponding to the uplink commands are retrieved from the source through the established connection. The retrieved aircraft software parts are stored in a portable data processing system. The portable data processing system is disconnected from the ground network. The portable data processing system is connected to an aircraft network in an aircraft. An uplink command is issued from the uplink commands to the aircraft network through an on ground component in the portable data processing system. A stored aircraft software part corresponding to the uplink command is sent to the aircraft network through the on ground component.
摘要:
A computer implemented method, apparatus, and computer program product for managing aircraft software parts. In one embodiment, a computer implemented method creates an alternate parts signature list part having a set of signatures for a set of stored aircraft software parts. The alternate parts signature list part is distributed to the aircraft data processing system. Each signature for a set of stored aircraft software parts on the aircraft data processing system is replaced with a corresponding signature in the alternate parts signature list part to form a set of current signatures on the aircraft data processing system.

A computer implemented method, apparatus, and computer program product for transferring information with an aircraft. A connection is established between an onboard electronic distribution system executing in an aircraft data processing system in the aircraft and an on ground component. Responsive to a request for a command from the on ground component, the command for execution is identified. The identified command is sent to the onboard electronic distribution system from an on ground component. A transaction identifier is assigned to the command. A transaction associated with the command is maintained on the onboard electronic distribution system and the on ground component using the transaction identifier. An uplink is initiated by the on ground component. An aircraft software part is sent to the onboard electronic distribution system from the on ground component to perform the uplink. A status of a transfer of the aircraft software part on ground component is stored.

摘要:
A system and method for validating software parts on an aircraft. A first hash value is calculated for a software part on the aircraft. A determination is made on the aircraft as to whether the first hash value matches a second hash value from a software integrity data structure stored on the aircraft. The software integrity data structure comprises the hash values that are not determined on the aircraft for the software parts used by the aircraft. A validation status is provided based on whether the first hash value matches the second hash value. An operation is performed on the software part on the aircraft only if the first hash value matches the second hash value.
摘要:
Methods, apparatus and computer program products are provided to authenticate and determine the integrity a software part. In this regard, a software part is authenticated and its integrity is determined by determining a first hash of the digital data that comprises the software part. If the air vehicle lacks data communications connectivity with an off-board security system, the method determines the authenticity and integrity of the software part by decrypting an encrypted hash of a software part in accordance with a public-private key pair to create a decrypted hash, comparing the first hash with the decrypted hash and transmitting the first hash to the off-board security system once data communications connectivity is established. Conversely, if the air vehicle has data communications connectivity with the off-board security system, the method determines the integrity of the software part by transmitting the first hash to the off-board security system for comparison with a whitelist.
